Microsoft SC-100 Practice Test 39

Question 380

During a security architecture workshop, the team learns that: The security architect wants to prioritize tenant security improvements but cannot quantify the impact of disrupting daily collaboration. What should the cybersecurity architect recommend?

  1. Normalize posture assessment for licensed controls, coverage and business-critical workloads.
  2. Rank Microsoft 365 hardening measures by exposure, business dependencies and tested rollout impact.
  3. Evaluate Microsoft Secure Score recommendations and effective protection for Microsoft 365 workloads.
  4. Distinguish Secure Score acceptance states from verified technical control enforcement.

Explanation

Correct Answer

B:

Security priorities should integrate risk reduction and operating continuity. This choice directly fits the stated architecture requirement.

Incorrect Answers

A:

This recommendation fits a different scenario: An architect compares two Microsoft 365 tenants' security scores without considering their different licensed feature sets. Raw score comparison may be misleading when the set of eligible assessed controls differs. It does not solve the specified case, for which Rank Microsoft 365 hardening measures by exposure, business dependencies and tested rollout impact. is appropriate.

C:

This recommendation fits a different scenario: A collaboration tenant has several risky sharing settings but leadership only tracks purchased security licenses. Security product licensing does not establish that recommended controls are enabled. It does not solve the specified case, for which Rank Microsoft 365 hardening measures by exposure, business dependencies and tested rollout impact. is appropriate.

D:

This recommendation fits a different scenario: A Secure Score rises after a control receives an exception status although the underlying user access configuration is unchanged. Assessment scores may not prove an unsafe configuration has been repaired. It does not solve the specified case, for which Rank Microsoft 365 hardening measures by exposure, business dependencies and tested rollout impact. is appropriate.

Question 381

A multinational enterprise reports this risk: A system passes load testing yet has no procedure to rotate its encryption keys. Which change MOST directly mitigates the design gap?

  1. Assess both Security and Reliability pillars when selecting recovery credentials and failover designs.
  2. Evaluate the security and operational tradeoffs of private endpoints, DNS and service integration.
  3. Balance measurable security risk reduction with cost, performance and operating constraints.
  4. Include operational key lifecycle and recovery checks in the architecture review.

Explanation

Correct Answer

D:

A technically functional workload can still violate security design principles when cryptographic operations are unmanaged. This choice directly fits the stated architecture requirement.

Incorrect Answers

A:

This recommendation fits a different scenario: A team treats availability and security as unrelated disciplines while its recovery mechanism uses long-lived privileged secrets. Cross-pillar architecture avoids resilient infrastructure that exposes excessive privilege. It does not solve the specified case, for which Include operational key lifecycle and recovery checks in the architecture review. is appropriate.

B:

This recommendation fits a different scenario: A solution proposes public endpoints for a regulated database solely because private connectivity adds deployment effort. Well-Architected design evaluates risk and operability, not just fastest initial provisioning. It does not solve the specified case, for which Include operational key lifecycle and recovery checks in the architecture review. is appropriate.

C:

This recommendation fits a different scenario: A product team enables every expensive defense feature without defining risk or budget limits. Architecture choices should be proportionate to business exposure and sustainable operations. It does not solve the specified case, for which Include operational key lifecycle and recovery checks in the architecture review. is appropriate.

Question 382

An architecture approval board must resolve this concern: An architect designs a data-sharing workflow without recording who the data controller and processor are. Which architecture recommendation BEST addresses the case?

  1. Document data ownership, processing roles and third-party responsibilities in the compliance architecture.
  2. Translate legal and contractual duties into specific classification, access, audit and retention controls.
  3. Perform a requirements-to-controls gap analysis covering residency, access, lifecycle and incident obligations.
  4. Establish approved records schedules with owners, triggers and conflict-resolution procedures.

Explanation

Correct Answer

A:

Accountability boundaries determine who may process and protect regulated information. This choice directly fits the stated architecture requirement.

Incorrect Answers

B:

This recommendation fits a different scenario: A healthcare workload has a privacy requirement written only as 'secure all records' with no measurable technical criteria. Actionable control statements make compliance requirements testable. It does not solve the specified case, for which Document data ownership, processing roles and third-party responsibilities in the compliance architecture. is appropriate.

C:

This recommendation fits a different scenario: A security team declares that encrypting data at rest automatically satisfies every national data-protection law. Encryption addresses only part of a broader compliance obligation. It does not solve the specified case, for which Document data ownership, processing roles and third-party responsibilities in the compliance architecture. is appropriate.

D:

This recommendation fits a different scenario: Two business units interpret the same retention rule differently and delete audit evidence at inconsistent times. Uniform retention policy interpretation prevents accidental loss or unnecessary preservation. It does not solve the specified case, for which Document data ownership, processing roles and third-party responsibilities in the compliance architecture. is appropriate.

Question 383

A security engineering lead describes the following problem: A compliance reviewer needs to discover current sensitive information across Microsoft 365 before defining new prevention rules. Which action is MOST appropriate for the stated need?

  1. Design Purview retention labels or policies independently of recovery backups.
  2. Configure supported sensitivity label encryption and recipient permission settings.
  3. Use Purview content classification and Content explorer with appropriate access controls.
  4. Extend supported Purview DLP policy coverage to eligible Teams and SharePoint locations.

Explanation

Correct Answer

C:

Data inventory and classifier coverage should inform restrictive policies. This choice directly fits the stated architecture requirement.

Incorrect Answers

A:

This recommendation fits a different scenario: A legal team requires contracts retained for a defined term but an architect proposes only operational backups. Record preservation and restore-point recovery address different objectives. It does not solve the specified case, for which Use Purview content classification and Content explorer with appropriate access controls. is appropriate.

B:

This recommendation fits a different scenario: A confidential Word document needs encryption to approved groups rather than a visible classification banner only. Labels must include actual protection rules to restrict access cryptographically. It does not solve the specified case, for which Use Purview content classification and Content explorer with appropriate access controls. is appropriate.

D:

This recommendation fits a different scenario: Employees share a customer spreadsheet through Teams but the organization has configured DLP only for Exchange Online. DLP policies protect only the selected workloads and supported content paths. It does not solve the specified case, for which Use Purview content classification and Content explorer with appropriate access controls. is appropriate.

Question 384

A governance team has raised this design requirement: An auditor asks why a posture finding was accepted as risk but the security team has no exception owner or expiration. What should the cybersecurity architect recommend?

  1. Route security findings to accountable resource owners with severity-based response service levels.
  2. Correct the infrastructure templates and apply preventive configuration policy to stop regression.
  3. Implement connector coverage reviews tied to onboarding and organizational inventory changes.
  4. Document risk acceptance with compensating controls, approval and periodic reassessment.

Explanation

Correct Answer

D:

An exception is a governed risk decision rather than silent closure of an assessment. This choice directly fits the stated architecture requirement.

Incorrect Answers

A:

This recommendation fits a different scenario: Alerts from hybrid servers are sent to a shared inbox that has no assigned responder. Detection without response ownership is not an operational control. It does not solve the specified case, for which Document risk acceptance with compensating controls, approval and periodic reassessment. is appropriate.

B:

This recommendation fits a different scenario: A posture program repeatedly fixes one storage setting only for deployment scripts to recreate the weakness. Systemic remediation addresses the source of recurring drift rather than individual instances. It does not solve the specified case, for which Document risk acceptance with compensating controls, approval and periodic reassessment. is appropriate.

C:

This recommendation fits a different scenario: An enterprise has no process to re-evaluate cloud connectors after a merger adds new subscriptions and accounts. Security coverage must evolve with the managed environment or newly onboarded accounts will remain invisible in posture reports. It does not solve the specified case, for which Document risk acceptance with compensating controls, approval and periodic reassessment. is appropriate.

Question 385

A regulated organization needs a safer design because: An organization has not decided when an incident commander may disconnect an infected plant network. Which change MOST directly mitigates the design gap?

  1. Include identity credential and session containment in the ransomware recovery architecture.
  2. Define and rehearse an incident containment decision tree with safety and business continuity approvals.
  3. Segment management and backup control planes from ordinary user endpoints with restrictive access paths.
  4. Combine endpoint detection, least-privilege write access and protected recovery controls as layered ransomware defense.

Explanation

Correct Answer

B:

Preauthorized containment criteria shorten response without overlooking industrial safety and essential operations. This choice directly fits the stated architecture requirement.

Incorrect Answers

A:

This recommendation fits a different scenario: A security architect designs recovery solely around restoring virtual machines and excludes compromised identity tokens. Restoring servers without closing attacker access allows reinfection from surviving accounts and sessions. It does not solve the specified case, for which Define and rehearse an incident containment decision tree with safety and business continuity approvals. is appropriate.

C:

This recommendation fits a different scenario: A compromised employee laptop can reach backup management and domain administration interfaces directly. Network segmentation and privileged access separation constrain ransomware movement from a single workstation. It does not solve the specified case, for which Define and rehearse an incident containment decision tree with safety and business continuity approvals. is appropriate.

D:

This recommendation fits a different scenario: Ransomware encrypts ordinary file shares even though the firm deploys antivirus on each endpoint. An endpoint antivirus agent alone does not limit unauthorized modification of broadly writable shared files. It does not solve the specified case, for which Define and rehearse an incident containment decision tree with safety and business continuity approvals. is appropriate.

Question 386

A cybersecurity architect is evaluating the following business requirement: The enterprise deploys privileged workstations but never verifies their patch level or security baseline compliance. Which architecture recommendation BEST addresses the case?

  1. Enforce monitored configuration baselines and update compliance for privileged access devices.
  2. Require hardened privileged access workstations and validated device posture for administrative sessions.
  3. Route remote administration through controlled jump hosts or approved privileged access paths.
  4. Separate daily productivity and administrative identities, profiles and device contexts.

Explanation

Correct Answer

A:

A special device label does not guarantee its actual protection state. This choice directly fits the stated architecture requirement.

Incorrect Answers

B:

This recommendation fits a different scenario: Privileged administrators use unmanaged laptops for production access from public networks. Dedicated secured devices reduce exposure to theft of sensitive management credentials. It does not solve the specified case, for which Enforce monitored configuration baselines and update compliance for privileged access devices. is appropriate.

C:

This recommendation fits a different scenario: A company permits RDP directly to tier-zero servers from every corporate workstation. Restricted ingress protects management interfaces from broad internal lateral movement. It does not solve the specified case, for which Enforce monitored configuration baselines and update compliance for privileged access devices. is appropriate.

D:

This recommendation fits a different scenario: An administrator performs routine web browsing in the same browser profile used for tenant-wide privileged sessions. Privileged session isolation reduces exposure to malicious web and email content. It does not solve the specified case, for which Enforce monitored configuration baselines and update compliance for privileged access devices. is appropriate.

Question 387

A hybrid-cloud design review identifies this security gap: An emergency code change bypasses tests and a release has no rollback plan. Which action is MOST appropriate for the stated need?

  1. Enforce reviewed infrastructure-as-code and policy-as-code for production changes.
  2. Define minimum security gates, emergency approval and verified rollback for accelerated releases.
  3. Revoke leaked credentials, migrate secret storage and prevent recurrence with secret scanning.
  4. Integrate SAST, SCA and image checks according to artifact risk and deployment stage.

Explanation

Correct Answer

B:

Incident urgency does not eliminate the need for controlled changes. This choice directly fits the stated architecture requirement.

Incorrect Answers

A:

This recommendation fits a different scenario: Engineers edit production infrastructure manually because security policy is not encoded in deployment templates. Declarative controls make deployment security consistent and reviewable. It does not solve the specified case, for which Define minimum security gates, emergency approval and verified rollback for accelerated releases. is appropriate.

C:

This recommendation fits a different scenario: Developers commit API keys to a public repository and assume deleting the line makes the secret safe again. A previously exposed credential may remain copied after a Git commit is removed. It does not solve the specified case, for which Define minimum security gates, emergency approval and verified rollback for accelerated releases. is appropriate.

D:

This recommendation fits a different scenario: An application pipeline checks syntax but does not test dependency vulnerabilities or container images. Different scans cover distinct vulnerability classes across source and dependencies. It does not solve the specified case, for which Define minimum security gates, emergency approval and verified rollback for accelerated releases. is appropriate.

Question 388

During a security architecture workshop, the team learns that: An organization expects secure web gateway logs to replace every application-specific audit event. What should the cybersecurity architect recommend?

  1. Retain workload audit sources alongside SWG traffic logs for sensitive application actions.
  2. Evaluate Microsoft Entra Internet Access secure web gateway policies for supported user traffic.
  3. Separate private application access design from general internet secure web gateway policy.
  4. Validate Global Secure Access client and forwarding profile prerequisites before rollout.

Explanation

Correct Answer

A:

Network access observations do not contain all business transactions or data modifications. This choice directly fits the stated architecture requirement.

Incorrect Answers

B:

This recommendation fits a different scenario: Remote users browse risky internet destinations from unmanaged networks without a consistent web security policy. A cloud-delivered SWG can apply identity-aware controls to internet access. It does not solve the specified case, for which Retain workload audit sources alongside SWG traffic logs for sensitive application actions. is appropriate.

C:

This recommendation fits a different scenario: A browser proxy architecture sends every private line-of-business app through ordinary public web filtering. Private resources and public internet destinations require different access routes. It does not solve the specified case, for which Retain workload audit sources alongside SWG traffic logs for sensitive application actions. is appropriate.

D:

This recommendation fits a different scenario: An architect wants to deploy secure web policies without verifying client support and traffic forwarding modes. Enforcement depends on the supported device and traffic acquisition path. It does not solve the specified case, for which Retain workload audit sources alongside SWG traffic logs for sensitive application actions. is appropriate.

Question 389

A multinational enterprise reports this risk: A domain-joined system is restored from an old image and its stored LAPS password no longer works. Which change MOST directly mitigates the design gap?

  1. Limit Windows LAPS password retrieval to approved roles and audit each retrieval.
  2. Configure supported Windows LAPS rotation and lifecycle policy for local administrator credentials.
  3. Plan supported local administrator password recovery and postrestore rotation validation.
  4. Deploy Windows LAPS or an appropriate managed local password solution with unique rotations.

Explanation

Correct Answer

C:

Device recovery must account for secret state changing since the image was created. This choice directly fits the stated architecture requirement.

Incorrect Answers

A:

This recommendation fits a different scenario: Help desk staff retrieve local recovery credentials through an unrestricted shared document. Recovery secrets should be accessible only to accountable operators. It does not solve the specified case, for which Plan supported local administrator password recovery and postrestore rotation validation. is appropriate.

B:

This recommendation fits a different scenario: A company rotates user passwords but leaves the built-in device-local administrator password unchanged for years. User credential rotation does not update independent local administrator secrets. It does not solve the specified case, for which Plan supported local administrator password recovery and postrestore rotation validation. is appropriate.

D:

This recommendation fits a different scenario: All branch laptops use the same static local Administrator password and one device is stolen. Unique per-device passwords prevent one disclosed local credential from working across the fleet. It does not solve the specified case, for which Plan supported local administrator password recovery and postrestore rotation validation. is appropriate.

Question 390

An architecture approval board must resolve this concern: A sensitive app requires new access checks when account risk changes after a session was established. Which architecture recommendation BEST addresses the case?

  1. Evaluate continuous access evaluation support and token revocation behavior for the protected workload.
  2. Apply an appropriately scoped Conditional Access authentication strength for the finance application.
  3. Stage Conditional Access rollout using report-only evaluation and tested emergency-access exclusions.
  4. Diagnose applied Conditional Access evaluations in the user's sign-in logs.

Explanation

Correct Answer

A:

CAE can respond to supported critical events without simply assuming every token expires immediately. This choice directly fits the stated architecture requirement.

Incorrect Answers

B:

This recommendation fits a different scenario: A finance app must require phishing-resistant sign-in from privileged staff regardless of their office network. Strong factor requirements should follow risk and resource sensitivity rather than location alone. It does not solve the specified case, for which Evaluate continuous access evaluation support and token revocation behavior for the protected workload. is appropriate.

C:

This recommendation fits a different scenario: An architect enables a tenant-wide block policy without testing emergency account access or report-only results. Controlled policy rollout prevents accidental loss of all tenant administration. It does not solve the specified case, for which Evaluate continuous access evaluation support and token revocation behavior for the protected workload. is appropriate.

D:

This recommendation fits a different scenario: An employee can open one app but another is blocked despite an accepted password. Access policy conditions can differ by app, device, user and sign-in context. It does not solve the specified case, for which Evaluate continuous access evaluation support and token revocation behavior for the protected workload. is appropriate.
